Obesity not only increases risk for morbidity/mortality, but also impacts the quality of life of obese individuals. In the United States, black women have the highest prevalence of obesity of any other group with approximately 80% of black women over age 20 having a body mass index (BMI)????25?kg/m2. We aimed to examine the association between BMI and quality of life in this high risk population compared to this association in white women, using the Impact of Weight on Quality of Life (IWQOL)-Lite questionnaire. Data from 172 black women (mean BMI?=?35.7; age?=?40.5) and 171 white women (mean BMI?=?35.5; age?=?40.4) were collected between 2000 and 2010 analyzed in 2010. The mean IWQOL-Lite total score was 81.6 for black women compared to 66.9 for white women, a statistically significant difference. Hierarchical linear regression models revealed a significant BMI-by-race interaction indicating that the relationship between BMI and IWQOL-Lite score was moderated by race. Our findings suggest notable differences in weight-related quality of life in black and white women. At similar BMIs, black women consistently reported better quality of life than white women on all IWQOL-Lite subscales. The greatest difference in IWQOL-Lite scores between black and white women was seen in the self-esteem subscale. Additional research is needed to understand how to incorporate the weight perspectives of black women into weight management messages and interventions. 相似文献

The goal of contemporary motor control theorist is the delineation of the “language” of movements. That is, in what unambiguous code are the parameters of movement specified, given the composition of the human body? In this pursuit not only are the elements of the language of movement sought, but the rules of combination or syntax of movement are also to be derived. This paper compares a number of motor control theories according to the form of control they exhibit and according to their ability to address issues in the area. Recurring theoretical trends in motor control are examined and the evidence for each is reviewed, emphasizing their explanatory power in the classical problems of control: motor equivalence (Hebb 1949), complexity (Bernstein 1967), and variability (Glencross 1980; Schmidt 1975, 1976). 相似文献

Influence of positive affect on the subjective utility of gains and losses: it is just not worth the risk 总被引:5,自引:0,他引:5
A modification of the procedure originally used by Davidson, Suppes, and Siegel (1956) to measure subjective utility was used to study the influence of positive affect on individuals' perceived value (utility) functions. Results indicated, as expected, that persons in whom positive affect had been induced showed a more negative subjective utility for losses than did controls. This indicates that losses seem worse to people who are feeling happy than to those in a control condition. The subjective utility functions of the two groups did not differ as much, however, when people were considering potential gain. Thus, at least in the situation tested in this study, potential gains did not seem to be more appealing (nor less so) for affect subjects than they did for controls. These findings are discussed in relation to theoretical issues in decision making and work suggesting that positive affect can promote increased sensitivity to losses in situations of potential meaningful loss. 相似文献

Women have been active in the American Psychological Association (APA) almost from the beginning. In general, however, they did not attain high-level office, editorships, and significant committee posts at the same level as their male counterparts. During one 51-year period, for example, no women were elected to the APA presidency. Despite protests, little changed. Finally, in the 1970s, the climate in the APA shifted. The Committee on Women in Psychology was formed, as was the APA Division of the Psychology of Women. From then on, women's issues have remained an important concern of the association. 相似文献

The present study investigated whether auditory temporal processing deficits are related to the presence and/or the severity of periventricular brain injury and the reading difficulties experienced by extremely low birthweight (ELBW: birthweight <1000 g) children. Results indicate that ELBW children with mild or severe brain lesions obtained significantly lower scores on a test requiring auditory temporal order judgments than ELBW children without periventricular brain injury or children who were full-term. Structural equation modeling indicated that a model in which auditory temporal processing deficits predicted speech sound discrimination and phonological processing ability provided a better fit for the data than did a second model, which hypothesized that auditory temporal processing deficits are associated with poor reading abilities through a working memory deficit. These findings suggest that an impairment in auditory temporal processing may contribute to the reading difficulties experienced by ELBW children. 相似文献

A common profile in English-speaking specifically language-impaired children is a moderate deficit across a broad range of linguistic features and a more marked, selective impairment in using bound morphemes and components of the verb system. To gain a clearer understanding of the nature of these more serious problems, we examined the speech of monolingual Italian-speaking as well as English-speaking children with specific language impairment. The evidence suggested that phonological factors contributed significantly to these children's extraordinary problems with particular linguistic features. Contrary to expectations, other marked deficits seemed more related to the opacity of the rules involved and homonymity with other morphemes than to problems with formal grammatical devices in general or components of the verb system in particular. 相似文献

Theory of mind, or mindreading, refers to our uniquely human capacity to infer what is in other people's minds. Recent research suggests that “implicit” elements of this ability can be seen as early as the second year of life, in infants’ spontaneous helping, communicative, and eye‐gaze behaviours. More “explicit” verbally mediated mindreading skills emerge in the preschool period, and these are positively linked to social competence. Research with typically developing children as well as those with autism spectrum disorders suggests that exposure to conversation about mental states promotes theory of mind development. 相似文献

The Influence of Time Estimation and Time‐Saving Preferences on Learning to Make Temporally Dependent Decisions from Experience 下载免费PDF全文
In this paper, we merge research related to experiential learning, temporal perception, and the value of time and money by examining decisions where the timing of action (response) determines the outcome received. We predicted that time‐saving preferences and impatience would decrease maximization (i.e., taking action when it returned the largest reward), and that the constraints of temporal perception would compound their effects. Across three studies, participants undershot on average (i.e., responded earlier than the period of time during which a response would return the maximal reward) showed a preference for shorter‐delay options and often did not find the maximal reward. In addition, participants' reliance on temporal perception increased undershooting, increased preferences for shorter‐delay options, and reduced maximization. Nevertheless, participants who found the maximal reward continued to maximize at a high rate rather than opting for shorter delays and smaller rewards. Thus, while most participants appeared to have a preference for saving time, most behaved as reward maximizers rather than temporal discounters. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

An unexplored aspect of contextual variation in emotion talk is the extent to which the emotions mothers and children discuss relate to the child, mother, or another self. To establish the extent to which mothers and children personalize the emotions they discuss, we examined the emotion talk of 40 American mother–child dyads in three conversational contexts: reminiscing, book reading, and play. We found that both mothers and children talked about emotions directly relevant to the child mostly in the reminiscing context and about emotions relating to another self mostly in the book context. Interestingly, the discussion of personalized emotions did not significantly differ between the book and play contexts, but did for the independent emotions. The discussion of mothers' own emotions occurred with almost the same frequency in all three contexts. In addition, within‐context analyses revealed that while mothers discussed the child's and their own emotions in the book and play contexts at about the same rate, children focused on their own emotions significantly more than on mothers' emotions in all three contexts. We contextualize the significance of the results in light of intervention programmes and future research. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
